How To Generate An Array Of Months Years Or Days In Javascript

Generating an array of months, years, or days in JavaScript can be useful for a variety of purposes.

It can help you create calendars, date pickers, and more. In this tutorial, we will show you how to generate an array of months, years, or days in JavaScript using simple code snippets.

Steps:

1. Generating an Array of Months:

To generate an array of months, we can use the built-in Date object available in JavaScript. The Date object provides several methods that allow us to get information about a specific date, including the month.

First, we will create an empty array to store the months. Then, we will use a for loop to iterate through the 12 possible months (January to December). Inside the loop, we will create a new Date object with the year set to 2000 (this can be any arbitrary year).

We will use the getMonth() method to get the numeric value of the month (0 for January, 1 for February, etc.) and push it to our months array.

Here’s the code to generate an array of months:

To check the output of the above code, you can log the array using console.log() or display it in the browser console:

[0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11]

2. Generating an Array of Years:

Similarly, to generate an array of years, we can use the same technique but with a for loop iterating through the desired range of years. Here, we will use the getFullYear() method to get the numeric value of the year.

Here’s the code to generate an array of years from 2000 to 2020:

To check the output of the above code, you can log the array using console.log() or display it in the browser console:

[2000, 2001, 2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015, 2016, 2017, 2018, 2019, 2020]

3. Generating an Array of Days:

To generate an array of days, we can use the same technique as before but this time we will use the getDate() method to get the numeric value of the day.

Here’s the code to generate an array of days in the month of March 2021:

To check the output of the above code, you can log the array using console.log() or display it in the browser console:

[1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31]

Conclusion:

In this tutorial, we showed you how to generate an array of months, years, or days in JavaScript using simple code snippets. By using these techniques, you can easily create calendars, date pickers, or other date-related applications in JavaScript.
